Advances in Electrophysiological Research

The discovery and recording of electrical activity (electroencephalography [EEG]) in the human brain in 1924 by the German physician Hans Berger (Collura 1993; Haas 2003) has led to numerous scientific breakthroughs and clinical applications (Borck 2005; Gloor 1994). Recording brain activity in humans using scalp electrodes provides a noninvasive, sensitive measure of ongoing brain function...

Common Biological Mechanisms of Alcohol Use Disorder and Post-Traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are highly comorbid. Although recent clinical studies provide some understanding of biological and subsequent behavioral changes that define each of these disorders, the neurobiological basis of interactions between PTSD and AUD has not been well-understood. In this review, we summarize the relevant animal models that parallel...

The Gastrointestinal Microbiome: Alcohol Effects on the Composition of Intestinal Microbiota

It has been estimated that approximately 2 billion people worldwide drink alcohol on a daily basis, with more than 70 million people having a diagnosed alcohol use disorder (World Health Organization 2004). Globally, alcohol use is the fifth leading risk factor for premature death and disability among people between the ages of 15 and 49 (Lim et al. 2012). Excessive alcohol consumption in the...

The Role of Innate Immunity in Alcoholic Liver Disease

Heavy consumption of alcohol poses a well-known health risk worldwide. Alcohol’s effects on health and well-being are numerous and include injuries and fatalities resulting from alcohol-induced incapacitation. Moreover, chronic and heavy alcohol consumption affects the integrity and function of vital tissues and organs, causing slow but significant structural and functional damage over time. One...

Bridging Animal and Human Models: Translating From (and to) Animal Genetics

Alcoholism is a complex disorder arising from a combination of genetic and environmental factors. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM–IV) (American Psychiatric Association 1994) requires that three of seven criteria be present during a 12-month period for a diagnosis of alcohol dependence. These criteria are tolerance, withdrawal symptoms, loss of control...

Identifying Prenatal Alcohol Exposure and Children Affected by It: A Review of Biomarkers and Screening Tools

Introduction

Although the awareness of the negative impact of prenatal alcohol exposure (PAE) was already alluded to in ancient writings1 and the impact of ethanol embryopathy in animal models was studied as early as 1910,2 the conceptualization of a syndrome associated with PAE was not recognized within modern medicine until the mid-20th century.3,4 The syndrome or disorder was not uniformly...

Community Indicators: Assessing the Impact of Alcohol Use on Communities

In the United States and other countries around the world, researchers have long been interested in community-level measurement of population health in the form of community indicators. Community indicators are measures that communicate information about a given dimension of a community’s well-being (Besleme and Mullin 1997). In the United States, the current popularity of community indicators can...

Hepatic Cannabinoid Signaling in the Regulation of Alcohol-Associated Liver Disease

Introduction

The prevalence of alcohol use disorder has been steadily rising around the world in recent years, and reducing the burden of alcohol-associated liver disease (ALD) caused by chronic alcohol consumption has become one of the most important global health issues.1,2 Excessive alcohol drinking (more than 40 g of pure alcohol per day) is closely associated with increased risk of all-cause...

Alcohol, DNA Methylation, and Cancer

According to the World Health Organization (WHO) Global Burden of Disease Project, alcohol accounts for approximately 3.2 percent of all deaths per year worldwide (corresponding to 1.8 million people) and is causally related to more than 60 different medical conditions (Rehm et al. 2004). Cancer formation (i.e., carcinogenesis) is one of the most significant consequences attributed to alcohol...

Racial/Ethnic Disparities in Mutual Help Group Participation for Substance Use Problems

Introduction

Racial/ethnic minority groups comprise a large proportion of the U.S. population and evidence a substantial need for treatment of substance use disorder (SUD). Analysis of the most recent, reliable data available—the 2018 National Survey on Drug Use and Health (NSDUH)1—found that the prevalence of past-year SUD among those age 12 and older was higher among some racial/ethnic minority...
